Question 10 (1 point) We are checking the costs of microwave oven repairs. Test whether Model A repair costs are lower than Model B's. We research the repair costs of 34 Model A ovens and 20 Model B ovens. The results on the repair costs are shown in the table below. Modem \" Model B 225 At a 0.10 level of signicance, are the costs of repair for Model A less than Model B? Assume the samples are randomly selected from the populations that are normally distributed. Assume the population variances are equal. Denote by #1 and #2 the mean repair costs for all Model A and Model B ovens, respectively. Test the appropriate hypotheses. What is the statistical decision? Interpret your decision. Ha and H1 are referred to an alternative hypothesis. O Reject Ho. There is no evidence that the costs of repair for the model A are less than model B. Q Do not Reject Ho. There is evidence that the costs of repair for the model A are less than model B. Q Do not Reject Ho. There is no evidence that the costs of repair for the modelA are less than model B. O Accept H1. There is evidence that the costs of repair for the model A are less than model B. O Reject Ho. There is enough evidence that the costs of repair for the model A are less than model B
